Interval exchange transformations and low-discrepancy

In Masur (Ann Math 115(1):169–200, 1982) and Veech (J Anal Math 33:222–272, 1978), it was proved independently that almost every interval exchange transformation is uniquely ergodic. The Birkhoff ergodic theorem implies that these maps mainly have uniformly distributed orbits. This raises the question under which conditions the orbits yield low-discrepancy sequences. The case of \(n=2\) intervals corresponds to circle rotation, where conditions for low-discrepancy are well-known. In this paper, we give corresponding conditions in the case \(n=3\). Furthermore, we construct infinitely many interval exchange transformations with low-discrepancy orbits for \(n \ge 4\). We also show that these examples do not coincide with LS-sequences if \(S \ge 2\).
